` Beit known that I, CHARLES T. STETSON,

e i U of Rockland, county of Plymouth, State of Massachusetts, have invented an Improvement in Machines for Channeling and Trimming Soles, of which the following description, in connecresenting like parts.

`This invention has for its obj ect theproduc-` i tion ofa machine by which to simultaneously channel and trim a sole in accordance with a pattern, and the machine is also arranged to groove the channel. i

j My invention consists, essentially,inapat j i 1. tern-plate and means to hold a piece of leather to be formed into a sole, and a carriage pro- `vided with a channeling and edgeftriinming device, combined with an endless chain or flexible connection to carry the said carriage about the pattern. a

Figurel in side elevation and partialsection represents a sole channeling and trimming maj `3 if chine embodying my invention, the same being also adapted to groove the channel; Fig.` 2, a

`side elevation, enlarged, of the holder for the "knives to be described Fig. 3, a top view thereof;` Fig. 4, aview of the right-hand end of Fig. 2,` Fig. 5, a detail of the channel knifel and a groover; Fig. 6, a sectionon the dotted linex \w,'Fig. 2; Fig. 7, a detail showing a part of showing the shape of 3 ofthe machine. 1

the holder and its` attached edge-trimming knife; and Fig.` 8, a diagram yon a small scale, the slot in the topplate The frame-work A has,a suitable bearing, A', to receivethe main driver-shaft A2, provided shaft, provided with a sprocket-wheel, A5, which receives about ita chain or flexible con-A nection, A, that is extended over a second sprocketfwheel, A7. `The horizontal upper plate of the framehas a slot, B, shaped as shown inthe diagram, Fig. 8, leaving a central detached part, B', which is sustained by the W- g `shaped bracket B2 Biattaehed to theframework A. This endless traveling chain or connection A6 has a pin, c, attached to one of its links, and the said pin has an arm or crank,

`a,fwhich in turn is provided at its other end and upper side, as in dotted lines, Fig. 1,with `a pin,which enters a plate, a2, fast on the lower end of a pin, c3, extended through the slot B, and connectedV with the lower end of the carriage-bed at, resting on thebed of the frame A. The plate B hasseveral posts, 2, terminated at top by a bar, 3, to which is adj ustably attached the sole-.pattern C, onwhich the piece of leather to be'tri'mmed and channeled rests. The carriagebed and its parts,to be described, are carried about the pattern-plate by the chain AG.

The carriage-bed.ctt hasupright side walls,

b, only one of which is shown in Fig. 1, and itis partially broken out, between which, in suitable ways, is placed a carriage, d, so that the latter may slide backward andforward therein. The carriage d has a rod, d', extended backward through a spiral spring, d2, and an adjustable hollow nut, d, held in an ear,A a, of the carriage-bed at.

The lever 6 pivoted4 on the ear a6 at e, has a riage, as shown in dotted lines, Fig. 1. The i spring d2 acts to press the pivoted knife-holding frameD against the edge of the pattern-A plate C, and the said frame turns more or less in the said carriage as the latter is carried about the pattern-plate.

` The base of the edge-trimming knife g is adj ustably held in the frame D by a grooved plate, y', and a screw, g2. The part g3 of the .frame D, (shown as `pivoted thereon at 94,) carries the channel-cutting `knife h, and the groover h2, and the presser-foot The shank h3 ofthe knife h is adjustably fastened to g3 bythe bolt ht, and the groover h2 by the bolt h, and the presserffoot is made adjustable by the screws m3 and mt. `The arm g3 iskept pressed down with the presser-foot against the face of the sole being channeled by a spring, mi, and the IOO N essere shown a lever by which the adjustment can be quickly made, and herein I may, if desired,

employ such a lever and parts as therein shown to adjust the channel-knife horizontally. n

The piece of leather to be cut into sole sh ape and channeled will be held down upon the patltern-plate C by the holder n, adjustably conto depress the cross-head u2.

nected with the cross-head n2, mounted on the rods n3, guided in suitable Ways of the framework A, and attached at their lower ends to a cross-bar, n4, which will have connected with it in any usual Way asuitabletreadle byl which The springs n act to elevate-the cross-head in the position Fig. l.

I claim- 1*." The pattern-plate, an endless belt or iexible connection, the carriage-bed connected to and made movable with the said belt about the pattern-plate. and the carriage D, combined with a knife-holdingframe pivoted in the said carriage, and provided with a channel-.knife and an edge-trimming knife, to operate sub 1 stantially as described.

2. The horizontally-adj ustable channel-knife and groover, the army g3 to carry them, the

edge-trimming knife, the pivoted knife-holding frame, the carriage, and the carriage-bed in which the carriage is adapted to slide toward and from the pattern-plate, combined with the stationary pattern-plate, the endless chain or connection with which the said carriagefbed is connected, and with means to move the said chain, substantially as and for the purposes set forth.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses. r
